Covering a WTA Vika/Serena match-up is always a blast. This time, itâs Istanbul. Not sure when or what round. I donât refer to other tennis sites (except for t3nnis.tv) on the grounds that they contain spoilers. Hell, I canât even explain how this tournament works. Itâs been described as âround robinâ, a term I remember from little league, but Iâm still drawing a blank.
